Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

screenshot scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 107 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Screenshot

Capture a screenshot of a URL or route. Nothing else — no tables, no analysis, just the image.

Arguments

  • {url-or-route} — URL or route path (default: /). If starts with /, prepends http://localhost:{DEV_PORT}.
  • --mobile — Resize viewport to 375x667 (iPhone SE) before capturing
  • --no-auth — Skip authentication (use for login page or public pages)

Configuration

Read cloudstack.json from the project root at the start of execution. Extract:

  • FRONTEND_PATH = frontend.path (default: web)
  • DEV_PORT = frontend.devPort (default: 5173)
  • UI_LIBRARY = frontend.uiLibrary (default: shadcn)
  • STATE_SERVER = frontend.stateManagement.server (default: tanstack-query)
  • STATE_CLIENT = frontend.stateManagement.client (default: zustand)
  • MULTI_TENANT = backend.multiTenancy (default: false)

If cloudstack.json does not exist, auto-detect by checking package.json dependencies.

Auth Configuration

Check cloudstack.json for localDev.authConfig:

{
  "localDev": {
    "authConfig": {
      "storageKey": "auth-storage",
      "state": {
        "isAuthenticated": true,
        "token": "dev-token"
      }
    }
  }
}

If localDev.authConfig is not present, use a generic dev auth pattern:

  1. Check for an auth store file (e.g., auth-store.ts, useAuthStore.ts) to find the localStorage key and expected shape
  2. Fall back to injecting: localStorage.setItem('auth-storage', JSON.stringify({ state: { isAuthenticated: true }, version: 0 }))

Process

Step 1: Resolve URL

If the argument starts with /, prepend http://localhost:{DEV_PORT}. Otherwise use the full URL as-is.

Step 2: Authenticate (unless --no-auth)

Skip this step if --no-auth is passed or the URL is not on localhost:{DEV_PORT}.

Navigate to http://localhost:{DEV_PORT} first to establish the origin, then inject auth via localStorage.

If localDev.authConfig is defined in cloudstack.json, use that directly:

localStorage.setItem('{storageKey}', JSON.stringify({authConfig.state}))

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
